Stabilization of oscillations in a phase transition model
(Wiley, 2017-02)
In this paper we analyze a model presenting formation of microstructure depending on the parameters and the initial data. In particular we investigate how the presence of stochastic perturbations affects this phenomenon ...

On the initial value problem for a class of nonlinear biharmonic equation with time-fractional derivative
(Elsevier, 2021-08)
In this work, we investigate the IVP for a time-fractional fourth-order equation with nonlinear source terms. More specifically, we consider the time-fractional biharmonic with exponential nonlinearity and the time-fractional ...

Pullback attractor for a dynamic boundary non-autonomous problem with Infinite delay
(American Institute of Mathematical Sciences, 2018)
In this work we prove the existence of solution for a p-Laplacian non-autonomous problem with dynamic boundary and infinite delay. We ensure the existence of pullback attractor for the multivalued process associated to the ...

A 3D isothermal model for nematic liquid crystals 1 with delay terms
(2022-08-01)
In this paper we consider a model describing the evolution of a nematic liquid crystal flow with delay external forces. We analyze the evolution of the velocity fi eld u which is ruled by the 3D incompressible Navier-Stokes ...

Existence and asymptotic behavior of solutions for neutral stochastic partial integrodifferential equations with infinite delays
(World Scientific Publishing, 2016-12)
In this work we study the existence, uniqueness and asymptotic behavior of mild solutions for neutral stochastic partial integrodifferential equations with infinite delays. To prove the results, we use the theory of resolvent ...

A STOCHASTIC THRESHOLD FOR AN EPIDEMIC MODEL WITH ISOLATION AND A NON LINEAR INCIDENCE
(AIMS Press, 2020-05-01)
In this paper, we study a stochastic epidemic model with isolation and nonlinear incidence. In particular, we propose a stochastic threshold for the model without any sharp su cient assumptions on model parameters as ...

Comportamiento asintótico en tiempo de ecuaciones en derivadas parciales no locales
(2016-06-23)
En las últimas décadas muchos investigadores han estado interesados en estudiar problemas no locales por su utilidad en las aplicaciones reales. En esta tesis doctoral se analizan ecuaciones parabólicas con difusión no ...

A new result on stabilization analysis for stochastic nonlinear affine systems via Gamidov’s inequality
(Springer, 2022-09)
The Lyapunov approach is one of the most effective and efficient methods for the inves tigation of the stability of stochastic systems. Several authors analyzed the stability and stabilization of stochastic differential ...

Attractors for Stochastic Lattice Dynamical Systems with a Multiplicative Noise
(2008)
In this paper, we consider a stochastic lattice di®erential equation with di®usive nearest neighbor interaction, a dissipative nonlinear reaction term, and a multiplicative white noise at each node. We prove the existence ...

Dynamics of a continuous Hénon model
(Wiley, 2018)
We study a continuous Hénon system obtained by considering the discrete original model in continuous time. While the dynamics of the continuous model is trivial, we are able to recover the complexity of the discrete model ...
